1) (62) is formed and this protrusion (61) is formed from the rear wall (23) side.
The stoppers (63) and (64) which can be engaged with (62) are formed to project. In addition, as described above, when the bearing surface (10a) of the rolling wheel (10) supports the rolling surface (11b) of the sorting cylinder (11) and is rotatable, the outer peripheral edge of the collar portion (11c). The guide rails (39) (40) have a slight gap (M), but the height from the rolling surface (11b) to the outer peripheral edge of the collar portion (11c) is (H), and Assuming that the distance from the bearing state of the rolling wheel (10) to the non-bearing position away from the rolling surface (11b) is (P), the rolling shaft (41) or (42) is set such that P> M + H. ) To the fitting portion (58) is set.

Therefore, when performing cleaning and inspection of the sorting cylinder (11) and the inside of the machine, the sorting cylinder (11) is pulled out of the machine. At that time, first, the cover (38) is attached to the support plate (27). )
After removing the transparent plate (36) and the opaque plate (37), the knob screw (32) is loosened to remove the shield plate (31) from the rear wall (23), and the cylindrical flange (35) is also removed. Both are taken out and the rear wall (23) is opened greatly. At this time, the gutter (12), the supply gutter (13), the sluice valve (30), etc. are supported in a cantilever manner on the free end side, which is the rear end, integrally with the support plate (27).

Also, the sensing valve (46) whose lower end is in the state of approaching the inner peripheral surface of the sorting cylinder (11) by the urging force of the weight (52) and whose upper end is kept in the state of approaching the inner peripheral surface of the sorting cylinder (11) are retained. The side plate (12b) of the receiving gutter (12) is rotated by the side plate (12b) as shown by an arrow (b) in FIG. 12, and the weight (52) is biased by the weight of the side plate (12b). Against this, the sluice valve (30) is tilted toward the supply gutter (13) side, and in conjunction with this tilting, the sensing valve (49) rotates as shown by the arrow (c) and together with the sorting cylinder (11). When the operation lever (57) is operated as indicated by the arrow (d), the straightening vane (47) is changed to a steeply inclined posture, and the upper edge (47a) of the straightening plate (47a) is separated from the inner peripheral surface.
Away from the inner surface of.

In particular, a lift shell bucket (19) for scooping up the sorted paddy is arranged on the inner peripheral surface on the terminal side of the lower selection cylinder (11). The inner diameter is narrow. That is, the phantom lines shown in FIGS. 9 and 10 represent the rotation locus (a) of the shell of the shell (19),

The top edge of is wrapped, but the side plate (12b) as described above
If the sensing valve (49) is moved away by the control lever (57) and the current plate (47) is moved away from the inner surface of the sorting cylinder (11) by the operating lever (57),
The lap state is eliminated as shown in FIGS. 11 and 12.

Further, the protrusions (61) formed on the grips (59) of the left and right cam bearings (D) engage with the stoppers (63) from above, and the rolling wheels (10) support the sorting cylinder (11). When the grip portion (59) is sequentially rotated as shown by the arrow (e) from the rotatable support state of FIG. 1, the projection (61) engages with the other stopper (64) as shown in FIG. The protrusions (62) formed at the corresponding positions corresponding to each other are engaged with the stoppers (63) to engage the rolling wheels (10).
The bearing surface (10a) is separated from the rolling surface (11b) of the sorting cylinder (11) in the supported state by the distance (P), and becomes the unsupported state.

(Actually, as shown in FIG. 2, the sorting cylinder (11) descends without being kept in a floating state, but this diagram is shown for ease of explanation.) Then, with this separated state, the sorting cylinder (11) descends, and the outer peripheral edge of the collar (11c) is guided by the guide rails (39) (4).
0), and at this time, there is a gap (X) between the outer peripheral edge of the collar portion (11c) and the bearing surface (10a) of the rolling wheel (10) as shown in FIG. .

Therefore, if the rear side of the sorting cylinder (11) is pulled out rearward, the front side of the sorting cylinder (11) will come out of the support state by the rolling wheels (9) and the outer peripheral edges of the front and rear collar portions (11c) will be guided. The rails (39) (40) are slid while being received and taken out of the machine.

When inserting the removed selection cylinder (11) into the machine body, the collar part (11c) is placed on the guide rails (39) and (40) and inserted, and the reverse process to the case of the above extraction is performed. Following this, the sorting cylinder (11) is restored to the supporting state, and the shielding plate (31) and the like are attached to the operating state.

If foreign particles such as pebbles are mixed in the mixed particles supplied to the sorting cylinder (11), the gutter (12) or the supply gutter (13) and the screw conveyors (28) and (29) installed therein. It will be caught in the gap during the rotation, and its rotation will be hindered, and the depreading roll (3) will be damaged.

In such a case, for example, as means for taking out foreign matter,
As shown in Fig. 16 to Fig. 16, the mixed grain tank (66) is interposed between the feed gutter (13) and the lower cylinder (65) for lifting the mixed grain obtained after the removal of the wind and the mixed grain is mixed. Means such as providing a sieve line (67) for receiving and sieving the mixed particles introduced from the thrower cylinder (65) in the tank (66) may be used properly.

In addition, as shown in FIG. 13 and FIG. 14, a sieve line (67) having an opening size enough to pass brown rice and paddy is provided, the lid body (68) is opened, and the outlet (69) is opened. Fig. 15 is a diagram showing an example of taking out foreign matter received on the sieve line (67), and the one shown in Fig. 15 is constructed so that the lid body (68) and the sieve line (67) are integrally rotated. Fig. 16 shows an example of removing the collected foreign matter from the outlet (69) by rotating it as shown by the phantom line. Fig. 16 shows the sieve line (67) installed obliquely in the mixed grain tank (66). The drawing shows a structure in which foreign matter is taken out from the outlet (69) while flowing down on the sieve line (67). In the figure, (70) and (71) are vertical diffuse reflection prevention plates. It is shown.

(G) Effect of the Invention As described above, the present invention supports a sorting cylinder, which has a large number of potholes formed on the inner peripheral surface thereof, by a plurality of rolling wheels and is horizontally movably mounted. In addition, in a pot-hole type sorting machine in which a gutter is inserted and laid horizontally in the sorting cylinder, in order to configure the sorting cylinder so as to be detachable in the rotation axis direction of the sorting cylinder, The wheel supporting the side is freely switchable between the bearing state and the non-bearing state in which it is separated from the peripheral surface of the sorting cylinder in this supporting state, and is fixed to the front wall and the rear wall of the machine body in the sliding direction of the sorting cylinder. Since the horizontally installed guide rail is located close to the lower side of the sorting cylinder and the sorting cylinder is configured to receive the sorting cylinder by the guide rail when switching to the non-supporting state, the rolling guide for rotatably supporting the sorting cylinder is provided. The wheels can be switched to the unsupported state in which they are separated from the peripheral surface of the sorting cylinder in the supported state. The guide rails, which are installed in the sliding direction of the sorting cylinder, will support the sorting cylinder from below, so the sorting cylinder does not interfere with the rolling wheels and is pulled out of the machine along the guide rail. It can be easily inserted into the machine and saves labor and trouble to facilitate smooth cleaning and inspection of the sorting cylinder and the inside of the machine. Since it is installed horizontally on the lower side, it has the feature of making the aircraft strong without hindering the selection due to the lifting action of the vase hole.
